  • a pharmaceutical composition comprising telmisartan as active ingredient, an alkalizer, a binder, a lubricant and isomaltose and to a process for the preparation thereof.
  • telmisartan is an active ingredient useful in the treatment of essential high pressure and also for the prevention of cardiovascular problems /e.g. myocardial attack, stroke/.
  • telmisartan in EP 1467712 two layer tablets comprising telmisartan and HCTZ /hydrochlorothiazide/ are disclosed.
  • One of the layers contains substantially amorphous telmisartan dissolved in a soluble matrix, while the other layer contains HCTZ in a disintegrating matrix.
  • the soluble matrix which contains the telmisartan comprises additionally an alkaline substance, a water soluble filler and optionally further auxiliary agents.
  • the alkaline substance may be an alkali hydroxide -e.g. sodium hydroxide or potassium hydroxide -, a basic amino acid -e.g.arginine, lysine - or meglumine.
  • suitable water soluble fillers which compensate the low solubility of telmisartan the following substances are mentioned: carbohydrates e.g. monosaccharides such as glucose; oligosaccharides such as saccharose, anhydrous lactose and lactose monohydrate; sugar alcohols e.g. sorbitol, mannitol, dulcitol, rhibitol and xylitol. Stress is laid on the importance of sorbitol as a particularly preferable representative of the water soluble fillers.
  • carbohydrates e.g. monosaccharides such as glucose
  • oligosaccharides such as saccharose, anhydrous lactose and lactose monohydrate
  • sugar alcohols e.g. sorbitol, mannitol, dulcitol, rhibitol and xylitol. Stress is laid on the importance of sorbitol as a particularly preferable representative of the water soluble fillers.
  • suitable hardness relates to a value above 100N, preferably above 130N.
  • the inventors referred to EP 1467712 and therefore carried out the experiments with sorbitol as selected sugar alcohol in order to produce tablets of suitable hardness.
  • the inventors found it as surprising that the hardness of the tablets depends on the specific surface rather than on the particle size of sorbitol.
  • suitable tablets hardness can be achieved with a specific surface of sorbitol of 0.75-3.5 m 2 /g, preferably 1.4-3.0 m 2 /g, particularly preferably 2.0-2.5 m 2 /g.
  • telmisartan can be significantly increased and in the place of the expensive and circumstantial powder drying the cheaper and more simple fluidization granulation can be used for the preparation of the telmisartan tablets.
  • the following water soluble fillers are enumerated: carbohydrates e.g. glucose; oligosaccharides e.g. sacharose; and sugar alcohols e.g. erithritol, sorbitol, mannitol, dulcitol, sorbitol and xylitol. Stress is laid on mannitol, erythritol, sorbitol and saccharose as particularly suitable water soluble fillers
  • telmisartan and HCTZ containing two layer tablets are prepared also by fluidization granulation and hereby a surfactant or emulsifier is used.
  • One layer of the tablet contains the telmisartan and the other the HCTZ in a disintegrating matrix.
  • telmisartan a tablet comprising telmisartan, sodium hydroxide, PVP, lactose monohydrate, crospovidone, meglumine, magnesium stearate and water is disclosed; the tablet contains no surfactant.
  • the two layer tablet set forth in IN 2009/MU02745 comprises no surfactant in the telmisartan containing layer and no disintegrant in the HCTZ containing layer.
  • the telmisartan is prepared by a process other than powder drying.
  • a telmisartan composition is disclosed which contains neither a surfactant, nor an emulsifier and is prepared by using the cheaper and more simple fluidization granulation in place of the powder drying.
  • the following fillers are enumerated: saccharose , lactose, mannitol, xylitol, sorbitol, maltitol, lactitol, erythritol, isomalt and mixtures thereof.
  • sorbitol Exemplified are sorbitol, mannitol, saccharose and lactose while sorbitol is mentioned as particularly preferable filler.
  • the reason thereof is that -compared to mannitol, saccharose and lactose - the use of sorbitol provides a higher total yield, the composition can be more readily tabletted and the tablets obtained are less brittle.
  • telmisartan containing composition crystalline telmisartan is dissolved in the aqueous solution of sodium hydroxide and meglumine, and thereafter Povidon K25 is added to the solution in order to stabilize the amorphous state of telmisartan.
  • the solution obtained is subjected to spray-drying in a drying column. This procedure results in the formation of an amorphous telmisartan powder.
  • the amorphous telmisartan is homogenized first with sorbitol and thereafter with magnesium stearate and finally pressed into tablets.
  • the drawback of the powder drying process is that the apparatus can be used only for this purpose and further equipment is required for the preparation of the product. Additionally the technology is energy intensive and a higher temperature must be used as compared to the fluidization granulation apparatus..
  • An object of the invention is the preparation of a telmisartan containing tablet composition which is resistant to the moisture content of the air and is therefore stable for a significantly longer period of time than the sorbitol containing tablets -s.g. Micardis -, and is bioequivalent with the tablets of the originator.
  • a further object of the invention is the elaboration of a simple high yield process for the preparation of the above telmisartan containing composition which is cheaper than powder drying.
  • Such a less hygroscopic tablet which resists to a higher extent to the moisture content of air can be packaged in a much more simple and cheaper way and this constitutes a further advantage.
  • telmisartan containing solution can be used to replace powder drying by spraying the telmisartan containing solution onto the isomalt while omitting the use of a surfactant or an emulsifier;
  • the granulate obtained can be more readily pressed into tablets with smaller losses;
  • An object of the invention is a pharmaceutical composition

  • telmisartan in the aqueous solution of the alkalizers, adding the solution of the binder, thereafter spraying the solution thus obtained onto the isomalt in a fluidization apparatus, homogenizing the granulate thus obtained with the lubricant and finally pressing the homogenized product into tablets.
  • neither a surfactant, nor an emulsifier not a disintegrant is used.
  • a surfactant nor an emulsifier not a disintegrant.
  • mannitol By way of experiment we have sprayed the telmisartan containing solution onto a mannitol containing fluid bed. We have chosen mannitol because this is a sugar alcohol chemically strictly related to sorbitol, it is considerably less water soluble and therefore it could be expected that mannitol would not be dissolved during granulation.
  • composition of the product thus obtained is as follows:
  • mannitol When using mannitol the problems occurring in the application of sorbitol did not take place i.e. mannitol was not dissolved in the granulating liquid even in case of a higher spraying speed of 7.2-7.8 g/min and the granulate particles formed did not stick together. However we have observed sticking or adhesion which made the tableting procedure more difficult and moreover a large number of waste tablets was formed. For this reason we have rejected the industrial scale use of mannitol.
  • microcrystalline cellulose as water insoluble auxiliary agent.
  • the fluidization granulation was successful, however the in vitro dissolution of the telmisartan composition prepared by using microcrystalline cellulose was very different from that of Micardis. Since due to this deviation the registration requirements relating to bioequivalence could not be fulfilled, we had to reject this solution as well.
  • the fluidization granulation of the telmisartan containing composition can be carried out by using a high spraying speed of 7.2-7.8 g min. even in the absence of a surfactant or an emulsifier.
  • the granules formed can be pressed to tablets in a significantly safer manner.
  • the easier tabletting manifests itself in two important respects.
  • a smaller number of waste tablets is formed; the yield of the isomalt technology is higher by 15 % than that of the mannitol procedure.
  • the surface of the tablets obtained by the isomalt procedure is more shining and no lubrication error occurs as happened in case of the mannitol containing tablets.
  • Isomalt is a disaccharide belonging into the group sugar alcohols and consisting of gluccopyranosyl-sorbitol /GPS/ and glucopyranosyl-mannitol /GPM .
  • the GPS:GPM ratio is 1 :1 .
  • Isomalt is a sugar alcohol of outstanding morphology, it consists of amorphous particles, is not polymorph, accordingly polymorph transformation is not to be feared with the progress of time.
  • the large specific surface of the amorphous particles guarantees a homogenous admixture of the active ingredient and the other active ingredients and no subsequent segregation takes place.
  • a further advantage resides in the fact that when using isomalt in the preparation of the telmisartan composition a disintegrant can be omitted because the tablets obtained possess outstanding dissolution and disintegration properties, If no disintegrant is used the composition of the tablet is more simple, the preparation of the tablets is more economical, better and also the load of the human organism by superfluous inactive synthetic substances is decreased.
  • the inorganic base content of the invention composition amounts to 1-2 % by weight, preferably 1.3-1.7 % by weight and particularly preferably 1.5 % by weight.
  • the organic base content of our composition is 1-10 % by weight preferably 4-8 % by weight and particularly preferably 5 % by weight.
  • the binder content of the our composition is 1-10 % by weight, preferably 4-8 % by weight and particularly preferably 5 % by weight.
  • the lubricant content of our composition is 0.3-2.0 % by weight, preferably 0.8-1.5 % by weight, particularly preferably 1 % by weight.
  • test conditions were as follows: The compositions were allowed to stand in Petri dishes, at 40°C and a relative moisture content of 75 % by weight for 4 weeks, in accordance with the Directive ICH Q1A R2/.
  • the percental water uptake of the Micardis composition is identical with that of sorbitol /31-32 %/ within the margin of error. Additionally since sorbitol is a high hygroscopic substance, the Micardis composition absorbs a large amount of water from the air. This is the reason why the Micardis compositions are put on the market in a three layer /OPA/PVC/ so-called "cold blister" packaging which protects the tablets from moistening and liquefying due to the effect of the moisture content of the air.
  • mannitol does not practically absorb water and the water absorption of the isomalt containing telmisartan compositions of the invention is about 6.5 % i.e. only one- fifth of that of the Micardis compositions.
  • the results of the above test are demonstrated in a spectacular manner on Figures 3-5 by showing the condition of sorbitol, isomalt and telmisartan compositions containing sorbitol and isomalt, respectively after 4 weeks of storage.
  • Figure 3 shows the condition of GalenIQ800 /isomalt/. It can be seem that under such conditions isomalt keeps its powder form.
  • Figure 4 shows the condition of sorbitol. The Figure clearly demonstrates that under the above conditions sorbitol is moistened under the effect of the moisture content of air and is fully liquefied.
  • Figure 5 shows the condition of tablets prepared by us containing GalenlQ 800 /isomalt/ and 40 mg of telmisartan in four Petri dishes. The left rear Figure shows the condition of our tablets comprising GalenlQ 800 /isomalt/ and 40 mg of telmisartan.
  • the left front Figure presents the condition of the tablets prepared by us, containing GalenlQ 800 /isomalt/ and 80 mg of telmisartan active ingredient.
  • the right rear shows the condition of the Micardis tablets containing sorbitol and 40 mg of telmisartan active ingredient; while the right front Figure shows the condition of Micardis tablets containing sorbitol and 80 mg of telmisartan.
  • Figure 6 presents a comparison of the dissolution /in a phosphate buffer,pH 7.5/ of the Micardis tablet comprising 80 mg of telmisartan and sorbitol with the isomalt containing telmisartan tablet according to the present invention.
  • the test conditions were as follows: the dissolving liquid /phosphate buffer/ was stirred with a paddle, at 75 rpm.
  • Moisture content not more than 7.0 %
  • Active ingredient content 95.0-105.0 %
  • compositions meet the requirements
  • the three layer Cold blister packaging provides a better protection against the moisture content of the air than the two layer PVC/PVdC packaging;
  • the active ingredient content of the mannitol containing tablets decreased with the progress of time in both the Cold blister and the two layer PVC/PVdC packaging, while on the other hand the active ingredient content of the isomalt containing invention tablets did not decrease in said packaging after the storing period of 4 weeks;
  • the invention composition shows an in vitro dissolution equivalent with that of the Micardis tablet of the originator.
  • the invention composition is not as strongly hygroscopic as the Micardis tablet, therefore our composition remains more stable than the sorbitol containing product for a significantly longer period of time and this enables the substitution of the expensive Cold blister packaging by a much cheaper packaging material, or -alternatively -if Cold blister is used, the shelf-time will lengthen.
  • the composition can be prepared in a fluidization granulating equipment generally used in pharmaceutical industry.
  • the granulate can be prepared directly after dissolving of the telmisartan and this results in a saving of energy; additionally fluidization is carried out at a lower temperature than powder drying which represents a saving of time since the homogenization step with sorbitol can be omitted.
  • fluidization granulation is performed with isomalt as filler -contrary to the use of sorbitol - there is no risk of the in situ dissolving of the isomalt filler. For this reason the telmisartan solution can be sprayed onto the isomalt with a higher spraying speed and this enables a rapid granulating step.
  • Fluidization granulation can be carried without using a surfactant and an emulsifier.
  • the technology is rendered more simple and the load of the human organism with pharmaceutically inactive excipients is reduced.
  • the preparation of the telmisartan composition does not require the use of a disintegrant because the isomalt containing tablets possess outstanding dissolution and disintegrating properties.
  • a further advantage of the isomalt containing invention compositions over the tablets containing sorbitol and mannitol is that it can be pressed more readily into tablets, because identical pressing strength provides higher tablet strength and better wear resistance.
  • the isomalt containing granules can be more easily pressed and with less losses than the sorbitol and mannitol containing granules and therefore - contrary to the use of sorbitol - there is no need of the use of a special specific surface variant.
